What is Avsola?

Avsola (infliximab-axxq) is a monoclonal antibody drug used to treat certain inflammatory autoimmune diseases. Avsola is a biological drug and one of four biosimilars of Remicade (infliximab). Biosimilars are highly similar versions of a drug that are designed to have the same effect, but they are not identical to the original version of the drug.

Avsola works the same as other versions of infliximab and blocks the damage caused by too much tumor necrosis factor-alpha (TNF-alpha). Avsola binds to TNF-alpha, which prevents it from interacting with its receptors and activating certain processes in your body.

TNF-alpha is a protein and inflammatory cytokine produced by your body, which plays an important role in your normal immune response. It is involved in your inflammatory response, and helps to fight off infection and cancer. Some people produce too much TNF-alpha, however, and this can cause an autoimmune disease to develop.

Avsola was approved by the US Food and Drug Administration (FDA) in 2019, more than 20 years after the original version of infliximab - Remicade - was approved.

What is Avsola used for?

Avsola is a prescription medicine that is approved for patients with:

• Rheumatoid Arthritis - adults with moderately to severely active rheumatoid arthritis, along with the medicine methotrexate.
• Crohn's Disease - children 6 years and older and adults with Crohn's disease who have not responded well to other medicines.
• Ankylosing Spondylitis in adults.
• Psoriatic Arthritis in adults.
• Plaque Psoriasis - adult patients with plaque psoriasis that is chronic (does not go away), severe, extensive, and/or disabling.
• Ulcerative Colitis - children 6 years and older and adults with moderately to severely active ulcerative colitis who have not responded well to other medicines.

It is not known if Avsola is safe and effective in children under 6 years of age.

Important information

Avsola may cause serious side effects, including:

1. Risk of infection

Avsola is a medicine that affects your immune system. Avsola can lower the ability of your immune system to fight infections. Serious infections have happened in patients receiving Avsola. These infections include tuberculosis (TB) and infections caused by viruses, fungi or bacteria that have spread throughout the body. Some patients have died from these infections.

• Your doctor should test you for TB before starting Avsola.
• Your doctor should monitor you closely for signs and symptoms of TB during treatment with Avsola.

Before starting Avsola, tell your doctor if you:

• think you have an infection. You should not start receiving Avsola if you have any kind of infection.
• are being treated for an infection.
• have signs of an infection, such as a fever, cough, flu-like symptoms.
• have any open cuts or sores on your body.
• get a lot of infections or have infections that keep coming back.
• have diabetes or an immune system problem. People with these conditions have a higher chance for infections.
• have TB, or have been in close contact with someone with TB.
• live or have lived in certain parts of the country (such as the Ohio and Mississippi River valleys) where there is an increased risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis). These infections may develop or become more severe if you receive Avsola. If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, or blastomycosis is common, ask your doctor.
• have or have had hepatitis B.
• use the medicines Kineret (anakinra), Orencia (abatacept), Actemra (tocilizumab), or other medicines called biologics used to treat the same conditions as Avsola.

After starting Avsola, if you have an infection, any sign of an infection including a fever, cough, flu-like symptoms, or have open cuts or sores on your body, call your doctor right away. Avsola can make you more likely to get infections or make any infection that you have worse.

2. Risk of Cancer

• There have been cases of unusual cancers in children and teenage patients using tumor necrosis factor TNF blocker medicines, such as Avsola.
• For children and adults receiving TNF blocker medicines, including Avsola, the chances of getting lymphoma or other cancers may increase.
• Some people receiving TNF blockers, including Avsola, developed a rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. Most of these people were male teenagers or young men. Also, most people were being treated for Crohn's disease or ulcerative colitis with a TNF blocker and another medicine called azathioprine or 6-mercaptopurine.
• People who have been treated for rheumatoid arthritis, Crohn's disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and plaque psoriasis for a long time may be more likely to develop lymphoma. This is especially true for people with very active disease.
• Some people treated with infliximab products such as Avsola have developed certain kinds of skin cancer. If any changes in the appearance of your skin or growths on your skin occur during or after your treatment with Avsola, tell your doctor.
• Patients with Chronic Obstructive Pulmonary Disease (COPD), a specific type of lung disease, may have an increased risk for getting cancer while being treated with Avsola.
• Some women being treated for rheumatoid arthritis with infliximab products have developed cervical cancer. For women receiving Avsola, including those over 60 years of age, your doctor may recommend that you continue to be regularly screened for cervical cancer.
• Tell your doctor if you have ever had any type of cancer. Discuss with your doctor any need to adjust medicines you may be taking.

See the section "What are the side effects of Avsola?" below for more information.

Who should not receive Avsola?

You should not receive Avsola if you have:

• heart failure, unless your doctor has examined you and decided that you are able to receive Avsola. Talk to your doctor about your heart failure.
• had an allergic reaction to infliximab products, or any of the other ingredients in Avsola. See below for a complete list of ingredients in Avsola.

What should I tell my doctor before receiving Avsola?

Your doctor will assess your health before each treatment.

Tell your doctor about all of your medical conditions, including if you:

• have or have had any type of cancer.
• have had phototherapy (treatment with ultraviolet light or sunlight along with a medicine to make your skin sensitive to light) for psoriasis. You may have a higher chance of getting skin cancer while receiving Avsola.
• have COPD, a specific type of lung disease. Patients with COPD may have an increased risk of getting cancer while receiving Avsola.
• have or have had a condition that affects your nervous system such as:
  • multiple sclerosis, or Guillain-Barré syndrome, or
  • if you experience any numbness or tingling, or
  • if you have had a seizure.
• have recently received or are scheduled to receive a vaccine. Adults and children receiving Avsola should not receive live vaccines (for example, the Bacille Calmette-Guérin [BCG] vaccine) or treatment with a weakened bacteria (such as BCG for bladder cancer). Adults and children should have all of their vaccines brought up to date before starting treatment with Avsola.

How should I receive Avsola?

• You will be given Avsola through a needle placed in a vein (IV or intravenous infusion) in your arm.
• Your doctor may decide to give you medicine before starting the Avsola infusion to prevent or lessen side effects.
• Only a healthcare professional should prepare the medicine and administer it to you.
• Avsola will be given to you over a period of about 2 hours.
• If you have side effects from Avsola, the infusion may need to be adjusted or stopped. In addition, your healthcare professional may decide to treat your symptoms.
• A healthcare professional will monitor you during the Avsola infusion and for a period of time afterward for side effects. Your doctor may do certain tests while you are receiving Avsola to monitor you for side effects and to see how well you respond to the treatment.
• Your doctor will determine the right dose of Avsola for you and how often you should receive it. Make sure to discuss with your doctor when you will receive infusions and to come in for all your infusions and follow-up appointments.

What should I avoid while receiving Avsola?

Do not take Avsola together with medicines such as Kineret (anakinra), Orencia (abatacept), Actemra (tocilizumab), or other medicines called biologics that are used to treat the same conditions as Avsola.

Children with Crohn's disease showed some differences in side effects of treatment compared with adults with Crohn's disease. The side effects that happened more in children were: anemia (low red blood cells), leukopenia (low white blood cells), flushing (redness or blushing), viral infections, neutropenia (low neutrophils, the white blood cells that fight infection), bone fracture, bacterial infection and allergic reactions of the breathing tract. Among patients who received infliximab for ulcerative colitis in clinical studies, more children had infections as compared with adults.

Tell your doctor about any side effect that bothers you or does not go away.

These are not all of the side effects with Avsola. Ask your doctor or pharmacist for more information.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Interactions

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. These include any other medicines to treat Crohn's disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis or psoriasis.

Know the medicines you take. Keep a list of your medicines and show them to your doctor and pharmacist when you get a new medicine.

Pregnancy and breastfeeding

Tell your doctor if you are pregnant or plan to become pregnant, or are breastfeeding or plan to breastfeed. You and your doctor should decide if you should receive Avsola while you are pregnant or breastfeeding.

If you have a baby and you were receiving Avsola during your pregnancy, it is important to tell your baby's doctor and other health care professionals about your Avsola use so they can decide when your baby should receive any vaccine. Certain vaccinations can cause infections.

If you received Avsola while you were pregnant, your baby may be at higher risk for getting an infection. If your baby receives a live vaccine within 6 months after birth, your baby may develop infections with serious complications that can lead to death. This includes live vaccines such as the BCG, rotavirus, or any other live vaccines. For other types of vaccines, talk with your doctor.
